After an absence of two months, I reopened my laptop, without updating Firefox 4.9. I installed Firefox 5.0 and since then Firefox is blocked asking to close down after earlier updates and preventing me from installing Firefox 5.0.

When I click on the Firefox icon on my desktop I receive the following error report: "Your computer must be restarted to complete previous update of Firefox. Do you want to reboot?

You apparently have Firefox checked in Tools > Options > Advanced > Update tab > Automatically check for updates to:.
If you want to install 5.0 then you have no option other than to reboot to complete the update. Then you can install v. 5.0.

Can I maually check for updates but prevent them from being automatically installed if it turns out one is available?

Can I maually check for updates but prevent them from being automatically installed if it turns out one is available?
Background:
In options I have "check for updates, but let me choose whether to install them" ticked. This works fine, in that I periodically receive a notice of an available update, and it will ask me whether I want to I want to install it.
But there are certain times -- for reasons I won't go into here (unless requested as part of seeking a solution) -- where I want to manually check for new versions, but RETAIN the ability to decide whether or not to install it. But if I click Help/About Firefox/Check for Updates, and it finds an update, it will immediately proceed to install it without asking for permission. While that seems quite inconsistent with my update preferences in Options, it is apparently normal behavior as described in https://support.mozilla.org/en-US/kb/update-firefox-latest-version#w_how-do-i-manually-check-for-updates.
So is there any way I can manually check for new-update availability but then refuse the update if I so choose? Once an unwanted install begins, I'm concerned that if I click cancel I could end up with a partial installation or some "messed up," duplicated or corrupted FF files (e.g., multiple versions appended with (1), (2) etc, similar to what sometimes confusingly happens when I do an XP System Restore).
Thanks.

I think what needs to be made very clear here is that when a user clicks on "check for updates" the software should bloody well CHECK for updates and most certainly SHOULD NOT proceed to download and apply any updates. this is misleading and intrusive.
I just wanted to check if there was an updated version but I DID NOT want to actually update at that moment. the software downloaded data, costing me money and tried to apply the update which could have potentially messed up my settings if I had not checked everything was ok first.
I actually discovered how to prevent the update by searching through windows and manually deleting the files but why should anyone have to go to such lengths?
the software should simply do as it is asked, not do things that have most certainly not been asked.

When I mouse over an active tab, a circular "block" symbol appears and prevents me from either clicking on or closing the tab

When I am in FireFox, and I mouse over any area that would normally allow me to do something, like select a tab, close a tab, or even fill text into this details box, a circular "block" symbol appears and prevents me from entering or doing anything. I have scanned all of the installed programs in the Control Panel and removed anything suspicious and reviewed addons and the like in FireFox, all to no avail. BTW, this problem does NOT occur while in Google Chrome, but I much prefer FireFox. Help!!!

Note that your System Details List shows multiple Flash plugins.

You can find the installation path of all plugins on the about:plugins page.
You can check the Flash player installation folder for multiple Flash player plugins and remove all (older) version(s) of the plugin (NPSWF32) and (re)install the latest Flash player.

Each song on my iTunes has a duplicate. How do I delete all duplicates and prevent this from happening again in the future?

Each song on my iTunes has a duplicate. How do I delete all duplicates and prevent this from happening again in the future?

After I had updated to Itunes 11 (also on Windows 7), I had the same experience, but I suspect that it was because I accepted a proposal to set up an external media library in order to simplify security backups. An associated result was that I had lost all of my playlists!
What I did was to restore the entire library off my Ipod, using a very good program called PodToPC (a free download is available) selecting an option to replace all of the stuff in the Itunes library. I use the Ipod Classic simply because it has a large capacity to hold my collection of CD and Vinyls. No way was I going to modify duplicates of 10000 tracks in 750 playslists by hand! I did have a few residual problems with some of the playlist specs but, after a few hours of work all was restored.
I hope this is useful.

HT4009 I make an In-App purchase and my device fails to complete the purchase. Could you do something about it and prevent it from ever happening again?

"A duplicate file name was specified", why is this poping up and preventing me from downloading from iTunes.

"A duplicate file name was specified", why is this poping up and preventing me from downloading from iTunes.

Try looking for and/or deleting incomplete downloads from the the iTunes Media folder. Then try downloading again, so its not resuming or overwriting a previous download.
Apple does have this article that talks about a very similar syncing error -> iTunes: Troubleshooting issues with third-party iTunes plug-ins.
WTH.

Is there a way to send an email and prevent it from being forwarded

Is there a way to send an email and prevent it from being forwarded

Not with the most common email systems - webmail, POP, SMTP or IMAP.
The only email system I know of that can prevent forwarding (or copying or printing) is Lotus Notes (now called IBM Notes). I believe it can technically be done within an MS Exchange environment, but I have never actually seen it implemented in one.

Snippet to start one an element and prevent another from starting

I need help. I need a snippet to start one an element and prevent another from starting. they are at the same place in the timeline and need to be there for other elements. but right now when I click one the other plays also how do I stop one from playing when the other is clicked?

I need it to show. its a header and a footer that move in and out. but they need to stay on the same timeline in order for the side controls that move in and out from the side. because when they play they move the header in and out. lol did you get that? Thanks for the comment.

I want to prevent history from being erases and prevent settings from being changed

I supervise the macs for a club and our policy is no nudity (porno,) lately we have been having a lot of trouble with that and in trying to track the culprits, they have started deleting the history. how can I prevent them viewing porno and /or prevent them from erasing the history? this has become a huge issue, we even have one person who has ended up in jail because of this.

You can't really prevent people from erasing the history. You will have to install a router with a (password protected) logging feature and reroute all computers through that router.
You posted with a Firefox 2.0.0.20 version, so I assume that the computer run an older Mac OS X 10.3.9 or earlier version. 
Are all computers old Macs that still have a Mac OS X 10.3.x or lower?

My macbook shuts off randomly, how do I know what's causing this and prevent it from happening again?

My macbook shuts off and I kept a journal for it because mine's got complications.

I spilled a cup of choclate milk on my keyboard, it was soaked! But my battery was drained so I know nothing had short out. So I turned it over and never tried to turn it on.
July 2
I went to the nearest apple center and asked them to clean it for me. (I knew it wasn't a good idea to clean it myself) They put it in a plastic bag but I asked them to open it as soon as possible so I know what parts are affected. They told me they'd take a picture of the inside for me and go back after an hour. Milk was still inside everywhere so I asked them to take it in.
July 8
I called to get an update on my mac and they said it wasn't economically practical to repair it because they recommended a full system replacement. I got depressed and accepted my Mac's fate. But what's annoying is I put my mac in on July 2 and they only tried to clean it in July 5 which makes me think that was the reason my mac was irreparable.
July 9
I took my mac and tried to find another opinion but I showed the diagnostics from the apple store and they said they couldn't fix it. My parents were getting ready to buy a new one.
July 13
I realized that my mac didn't have charge when milk spilled on it so I tried to charge it and BOOM IT OPENED. They keyboards were sticky and it takes a moment before my computer reacts to the trackpad but it works! Even all the keys works! But it doesn't charge.
After lunch, it was workingp perfectly and my batteries were at 30% charge! I was really happy!
(in the interval my mac works perfectly, it stays for normal 7 hours when battery is charged fully)
However at July 19
There was no electricity for four days (A typhoon came in the Philippines) and my battery is about 7% so I went to the public market to get it charge while I wait for electricity. I charged it for about 3 hours and sideways because it was inside my backpack while it charged so noone will notice it. When I got home and opened my laptop, it shut off randomly after my desktop appeared after start up. So I was sad.
July 20
I found a solution online to use the option-shift-power button my mac opened and worked normally!
July 21
My computer was normal in the morning then in the afternoon it shut off again after I waked it up from sleep. Tried option-shift for about 3-5 times before it worked with varying intervals from 5-20 minutes each
July 22
I get nervous when I use it but it worked perfectly I was even able to edit with Final-cut pro and HD clips.
Wednesday
Worked perfectly in the morning but in the afternoon, after waking it up from sleep it won't turn on tried the option-shift then I tried resetting the SMC for about three times (my mac is a unibody) but it didn't turn on the whole evening.
Today Thursday morning July 24
I tried to reset SMC first thing in the morning after the thing won't turn on. After about an hour, I tried to turn my mac on normally and it opened. So what I did is to back up all my files. (It took the whole afternoon) and at night I ran diagnostics (D during start up) and no threats were found
Haven't been experiencing the trouble, as of the moment I'm writing this Jul 25, Friday (12:13 AM) HK time Philippines.
So what I'm asking here is what do I do to make sure this doesn't occur anymore. I probably written a very detailed log. So what else (diagnostics and other) should I do to prevent this from happening again. School starts in August and I will need my laptop to work perfectly to let me go through college with less burden. Thank you and I hope you reply. Any more questions about details on my Mac will be answered

Get a new computer. Consider switching to regular milk, or even a light fruit juice.

I have recently installed Mavericks and since then I have been unable to shut down or log out of my mac. I work with two screens and now I seem to have programmes at the top of both screens which I didn't before. any advice?

I have recently installed Mavericks on my desk top and since then I have been unable to switch off my computer without crashing it. I work with two screen and now I seem to have the menu bar on the second screen as well which I did not have before. Can you please help me?

Dr Bettina, I had similar problems with Mavericks. I installed it on a Mini and a 13" MacBook Pro. I can't speak to your disdplay issues, but I can confirm the inability to logout, shut down, or restarft without a forced, power button shut down. I can also report frequent System Prefs freezes and finder issues, like folder contents taking half a minuite or more to render, or not appearing at all. And while a few Adobe CC apps actually ran faster, InDesign ran like molasses uphill in Decemner.
I tried uninstalling or disabling numerous 3rd party apps and pref panes. I unplugged everything but the keyboard, ran DiskWarrier, repaired permissions, did fsck -f, trashed various preference files, reinstalled the OS... You name it, and I tried it — short of a potion using eye of newt.
After two days of totally hosed productivity, I restored OS 10.8.5 on the Mini so I could actually get some work done. However, I've decided to leave Mavericks on the MBP as a sort of crash dummy, and will install and thoroughly test all updates until stability has been achieved. Then — and only then — will I upgrade the Mini to Mavericks, even if it means waiting 'til a .2 or even .3 update.
Good luck to you...

Is there a way to allow someone to play a keynote briefing and prevent them from copying, rewriting, or printing it?

Is there a way to allow someone to play a keynote briefing and prevent the user from copying, modifying, or printing it? The reason I ask this
is because I have created a lengthy keynote briefing book that has motion in it, and I don't want it copied, modified, or printed.

To lock a presentation : 1 Open the presentation you want to lock , and hold your pointer over the name of the presentation at the top of the Keynote application window. A triangle appears. 2 Click the triangle and choose Lock. To unlock a presentation for editing: Hold your pointer over the name of the presentation at the top of the application m window until the triangle appears, click the triangle, and then choose Unlock
Good luck

How can I remove an application icon from the loc. bar and prevent it from auto loading?

I don't know the "lingo" of how-to's with Firefox; but I subscribed to www.catalogchoice.org. Somehow, the icon appears to the right of my print icon in the location bar and automatically pops-up when I go to any website. I can't find how to remove it from the toolbar and remove it from Firefox. I cancelled my subscription with them but continue to have this annoyance.

Can you attach a screenshot?

Apps disappearing from my new iPad 2 after I joined the iCloud, then they show up on my PC iTunes! How can I prevent this from happening??

I just bought my first Apple computer - an iPad 2. I downloaded a bunch of apps and they showed up on my desktop and I was using them. I then turned on the iCloud function, and soon after all my apps were gone from the iPad. Today I just noticed that they now show up on my home PC iTunes under APPS. I don't want them there! How do I keep this from happening???

If you have iTunes 11 on your computer then you can enable the left-hand sidebar on it via option-command-S on a Mac, control-S on a PC - when connected (and if your computer's iTunes is up-to-date) your iPad should then appear on that sidebar under a 'Devices' heading :
If you select the iPad on that sidebar you can then use the Movies tab on the right-hand side of the iTunes screen to select and sync that film to your iPad's Videos app.
Has your iPad been synced to the computer before ? If not then you might find this page for syncing to a new computer useful : https://discussions.apple.com/docs/DOC-3141

When I use the brush or eraser, a Ø symbol pops up next to my cursor and prevents me from drawing a stroke. Does anyone know a solution to this issue?

Whenever I use the brush or eraser tool, during every other stroke, I get a Ø (circle with a line through it) sign next to the brush shape/cursor and can't draw. Please help, it's extremely frustrating and disrupting my workflow! I am drawing every animation frame so you can imagine, every other stroke is quite often.
There are locked layers below my active drawing layer, which makes me wonder if Flash is just trying to tell me I can't draw on those layers, but I know that Plus I need those layers there to guide my active layer's drawing. I've never run into this issue before with layers being locked and such. What am I missing?
Any insight is appreciated.
Thank you!

Hmm interesting theory...I do press undo a lot, but only because I'm trying to get a good-looking brushstroke down, usually I don't even actively lock a layer as a step during my session because they've already been locked previously and I don't need to lock/unlock them often. The thing that is frustrating is that I will try to make a stroke, and can't because the symbol pops up...then I'll make the exact same intended stroke again and then it will work fine. It's pretty haphazard but basically every other stroke or every few strokes, it'll pop up.
I think I'm beginning to almost accept this rhythm in my workflow
I'm using CS6, and I noticed that I don't have this problem when I bring the file to work on at my job (CS5) or at school (CC).
Edit: I tried to test your theory by drawing as much as I could without pressing undo...I was pleasantly surprised to not run into any issues with the paintbrush, but sure enough, as soon as I switched from the paint brush to the eraser, and tried to erase something I just drew, the eraser popped up with the "prohibited" symbol.
